xcb: Fix getting the primary screen from QXcbConnection::screens()

Currently getting QXcbScreen* for primary screen is too messy and it
wrongly uses QXcbConnection::primaryScreen() as an index in
QXcbConnection::screens() although QXcbConnection::screens() returns
the primary screen as the first item in the list since
3c8eb404877df9c967d81fa9df7d718c538fb407.

So to clear the API rename primaryScreen() to primaryScreenNumber(),
add QXcbConnection::primaryScreen() that returns correct QXcbScreen*
and use it directly.
